Re: [mapserver-users] PHP mapscript createLegendIcon doesn't follow style maxscaledenom

[Paul Moen]

In case anyone else wants the createLegendIcon to return the image based what 
would be drawn at the current mapscale, here is what I did.

In the mapserver 7.0.4 source code, mapscript/php/mapscript_i.c line 1116  has 
scale_independant hard coded to MS_TRUE.  I changed it to MS_FALSE, recompiled 
and have the behavior that I was expecting.  

Thanks,

I am finding that createLegendIcon returns a different legend item than what is 
used in the map output when using scaledenom in the style.
 
Below is a test script that produces what I am talking about. 
 
The script will create 4 images.
 
map_scale_873.png -> map->draw output with a 873 scaledenom
map_scale_2618.png -> map->draw with a 873 scaledenom
legimg_scale_873.png -> createLegendIcon output with a 873 scaledenom
legimg_scale_2618.png -> createLegendIcon output with a 873 scaledenom
 
 
I was expecting that the legend image at the 873 scale, legimg_scale_873.png 
would match the map output, map_scale_873.png.  Can anyone see a problem, is 
this a bug, or is this expected behavior?
 
selectOutputFormat('png');
$img=$map->draw();
$name=round($map->scaledenom);
$img->saveImage("map_scale_$name.png");
$tmpLay =$map->getLayer(0);
$tmpclass = $tmpLay->getClass(0);
$tmpImg = $tmpclass->createLegendIcon(50,50);
$tmpImg->saveImage("legimg_scale_$name.png");
$map->setextent(200,200,300,300);
$img2=$map->draw();
$name=round($map->scaledenom);
$img2->saveImage("map_scale_$name.png");
$tmpImg->saveImage("legimg_scale_$name.png");
